*Physics 11* – The main goal for today was for students to investigate wave interference and standing waves. However, I started the class off with some voting questions using the wave equation. As you can see above, this was not time wasted. Everyone clued in on the second round of voting and could explain their mistakes.

I’m using distributed practice for the wave equation. Students have done a bit of practice over 3 days. I still haven’t given them a worksheet on it. Maybe we’ll get to this next class. By the time they are quizzed on it, they will have practiced this equation/idea over 3 classes with each class spaced over 2-4 days apart.
